Using 3dFWHMx & 3dClustSim for clusterwise correction in SPM?

WebDec 8, 2016 · I just had a hunch from playing around with some synthetic gaussian spatial ACF images that the 3dFWHMx’ s ACF ‘a’ parameter’s upper limit is 0.9940 and hence … WebMar 1, 2024 · We estimated the spatial smoothness of the residuals for each participant using a Gaussian plus mono-exponential function implemented with 3dFWHMx. The spatial autocorrelation function values were determined for each participant using the “-acf” option, and the mean values across participants (0.761, 2.956, 11.06) were calculated (Cox et al ... dadi in english word WebAug 9, 2012 · We’re using AlphaSim to estimate a cluster extent threshold for our group maps, and a reviewer for one of our articles suggested that we must used 3dFWHMx to estimate the true smoothness in X, Y, and Z rather than just putting the size of the blur we applied to the data (using the -FWHM option). We applied a 3.5mm FWHM blur to the … WebI realize that I need to use 3dClustsim in combination with 3dFWHMx: This seems to be the latest bid. And I know this is a work in progress, much like is suggested by Bob's reply in … dad ignores my texts Web3dFWHMx -mask mask_group+tlrc -input errts.sub-01_REML+tlrc -acf Which will output numbers like the following: 0.827124 2.9802 5.31313 7.16512 The first three numbers are the parameters needed to create the autocorrelation function, a model of how correlated a given voxel is with its neighbors; the last number is the estimated smoothness of the ...
